I build systems that make your knowledge visible and your identity coherent

I'm Jason Yergeau, a developer and strategist based in Haarlem. I design and build websites, web applications, and publishing systems for teams whose work is richer than the templates they are given.

Over twenty years of engineering I've seen the same pattern: organisations are dense with knowledge, research, experiments, and ongoing activity, yet their public presence reflects only a fraction of it. The problem is rarely output. It's structure. Without structure, what is known internally never coheres externally.

I build editorial systems architecture. I start with what you already know, what you are working on, and where you are heading. I extract and stabilise those patterns, define guardrails, and design pipelines that turn them into structured, repeatable public presence. My own homepage works this way. The central essay is written by hand. Around it, a system expands outward: surfacing references, generating annotations, linking related threads, and shaping a broader field of context. The original voice remains intact. The surrounding layer deepens it without interrupting my flow as a writer.

The result can be a website, a content platform, or short-form video. Underneath, the logic is the same: structured knowledge feeding a durable publication system. As your work evolves, the system evolves with it. You are not locked into a platform or dependent on a vendor. You own the architecture.

For teams who simply need a new site, I design and ship that quickly. For teams who want more, I build the infrastructure that turns ongoing work into continuous presence.

If you are a creative agency, brand, or knowledge-driven team that wants its public output to reflect the depth of its thinking, see what I offer or get in touch directly.
